摘要:
A hydraulic control apparatus for controlling a hydraulically-operated power transmitting system for an automotive vehicle, the power transmitting system including a continuously variable transmission and an auxiliary transmission coupled to the continuously variable transmission. The auxiliary transmission has a first and a second forward-drive position relating to a high and a low speed range, respectively, which high and low speed ranges are selected by an operator controlled shift lever. The hydraulic control apparatus comprises a shift valve controlled by an electric control signal so as to be placed selectively in one of a high-range position and a low-range position to place the auxiliary transmission in the first and second forward-drive positions, respectively. The control apparatus further comprise a lock device for holding the shift valve in the high-range position, irrespective of the electric control signal, while the high speed range is selected by the shift lever.

A control apparatus for a dazzle-free reflection mirror of a vehicle is disclosed. The control apparatus is provided with a rear light sensor and a circuit for driving the reflection mirror into a dazzle-free operation in accordance with the intensity of the rear light detected by the rear light sensor when a light switch is turned on. The control apparatus is further provided with a mirror adjusting device for adjusting the reflection angle of the reflection mirror and a detecting circuit for detecting the adjusting operation of the mirror adjusting device. When the detecting circuit detects the adjusting operation, the dazzle-free operation of the reflection mirror is disabled even if intensive light is incident to the reflection mirror from the rear of the vehicle.

In a vehicle having an interior room mirror and a pair of exterior right and left side mirrors, a single photo sensor is provided for detecting an intensity of light incident from the rear of the vehicle. A driving circuit drives both the room mirror and the side mirrors into a dazzle-free condition in common when the photo diode detects the intensive rear light. Alternatively two photo sensors are provided for detecting not only the intensity of the rear light but also direction of the rear light and both the room mirror and one of the right and left side mirrors are driven into the dazzle-free condition in accordance with both the intensity and direction of the rear light.

A continuously variable transmission (CVT) has input and output pulleys interconnected by a V-belt. The output pulley is actuated by a line pressure. A throttle pressure is increased as the position of an intake throttle valve arranged in an intake path is increased. A transmission-ratio pressure is decreased as the position of the intake throttle valve is increased. The transmission-ratio pressure is decreased in the region of smaller openings of the intake throttle valve more gently than in the region of larger ones. The line pressure is produced in relation to the throttle pressure and the transmission-ratio pressure.

A reflection mirror using a liquid crystal cell is disclosed. A first thin film consisting of one of magnesium difluoride, silicon dioxide, silicon monoxide or titanium dioxide is formed on a glass substrate supporting the liquid crystal cell and a thin aluminum film is formed on the first thin film as a reflection mirror layer. Adhesiveness of the thin aluminum film to the glass substrate is strengthened by the first thin film. A second thin film is formed on the thin aluminum film to protect the same from being hurt. The reflection mirror may be used as a dazzle-free reflection mirror of an automotive vehicle.

Disclosed herein are novel unsaturated cyclic amide-substituted ether compounds having a wide range of utility in crosslinking agents, adhesives, paints, raw materials for hygroscopic resins, etc. These compounds are prepared by reacting cyclic halogen-substituted ether compounds with unsaturated amide compounds in the presence of a strong basic substance in an aprotic polar solvent.

A method for controlling an engine using a continuously variable transmission, the method decreases the fuel consumption of the engine in a transient shifting condition. When the operator displaces the accelerator means and the magnitude of the difference between a steady state engine speed, which corresponds to the amount the throttle means of the engine is opened, and a previously detected engine speed differs from a predetermined constant value, the engine speed abruptly increases after a predetermined time elapses and thereafter the engine speed gradually changes to the steady state engine speed. The abrupt increases in the engine speed is a function of a vehicle speed and the amount of the throttle opening.

A coating apparatus comprising a support assembly, a support moving mechanism for pivotally moving the support assembly about a horizontal axis, an applicator supported by the support assembly upwardly and downwardly movably, a position detector for detecting the raised or lowered position of the applicator, a pair of distance sensors attached to the support assembly and arranged one above the other at a distance for detecting the distance from the work surface to be coated, and a control unit connected to the position detector and to the distance sensors for causing the support moving mechanism to pivotally move the support assembly in response to detection signals from one of the distance sensors closer to the applicator to hold the applicator at a substantially constant distance from the work surface. Even when curved in the direction of the height, the work surface can be coated uniformly because the substantially constant distance is maintained between the applicator and the work surface.

A transmission control device, for a road vehicle with an engine and a transmission which has a gearbox which includes several fluid pressure activated friction engaging mechanisms and which can provide at least three forward speed stages according to selective supplying of actuating pressures to the friction engaging mechanisms, practices a transmission control method. An electrically actuated hydraulic pressure control device selectively supplies actuating pressures to the friction engaging mechanisms so as to engage any one of the forward speed stages i.e. gear ratios. An electronic control system repeatedly at short time intervals receives from a road speed sensor and an engine load sensor signals representative of road speed and of engine load, then determines a target speed stage, then determines a decided speed stage, and then energizes the hydraulic pressure control device to engage the decided speed stage. The decided speed stage is determined so as to cause, when the actual speed stage and the target speed stage differ by less than two speed stages, immediate shifting of the gearbox to the target speed stage; and is also determined so as to cause, when the actual speed stage and the target speed stage differ by two or more speed stages, at least sometimes shifting of the gearbox by steps of one speed stage at a time to the target speed stage, the shifts by steps being separated in time by at least a predetermined first time interval.
